N-body simulation
In
physics
and
astronomy
, an
N
-body simulation
is a simulation of a
dynamical system
of particles, usually under the influence of physical forces, such as
gravity
(see
n-body problem
).
N
-body simulations are widely used tools in
astrophysics
, from investigating the dynamics of few-body systems like the
Earth
-
Moon
-
Sun
system to understanding the evolution of the
large-scale structure of the universe
. In
physical cosmology
,
N
-body simulations are used to study processes of non-linear
structure formation
such as
galaxy filaments
and
galaxy halos
from the influence of
dark matter
. Direct
N
-body simulations are used to study the dynamical evolution of
star clusters
.
